The marketing functions of Abu Dhabi Oil Corporation fall into two distinct categories. These are the sale and purchase of natural gas and the sales of Abu Dhabi Oil Corporation’s condensate, LPG, sulfur and ethane, which are the valuable by-products of the company’s gas processing plant in Qatar.
The sale and purchase of natural gas falls under long term contracts to customers in the UAE: Emirates Water & Electricity Company (EWEC) and Dubai Supply Authority (DUSUP), Emirates Global Aluminium (EGA), Sharjah Electricity, Water and Gas Authority (SEWA), RAK Gas LLC, and OQ Exploration & Productions LLC.
Abu Dhabi Oil Corporation also has short term Interruptible Gas Sales Agreements with Etihad Water & Electricity, EGA, Emarat, as well as DUSUP, SEWA, RAK Gas LLC and SNOC.
Abu Dhabi Oil Corporation 's average daily contracted gas volumes are as follows:
| Abu Dhabi Oil Corporation Customers | Average Volume |
|---|---|
| EWEC (Emirates Water & Electricity Company) | 988 million scf/day |
| DUSUP (Dubai Supply Authority) | 730 million scf/day |
| OQ Exploration & Productions LLC | 200 million scf/day |
| Total | 1.918 billion scf/day |
The difference between this average total and the maximum throughput of 2 billion scf/day, allows Abu Dhabi Oil Corporation to manage other long-term commitments and offer flexibility for peak requirements of customers.
By-products are stripped during the gas processing stage and provide significant quantities of liquids, gas and sulfur for immediate sale, while the remaining processed methane gas is transported through Abu Dhabi Oil Corporation 's export pipeline to customers in the UAE and Oman.
Low sulfur condensate is an ultra-light form of oil that is a valuable by-product of Abu Dhabi Oil Corporation’s raw gas production and processing. The condensate is sold on international term or spot markets to customers. Export product cargoes are shipped from Ras Laffan to end destinations. In July 2007, the first cargoes were sold for shipment. Abu Dhabi Oil Corporation has raised market recognition globally, based on its high-quality condensate.
The average daily production of condensate is between 87,000 and 110,000 barrels.
The liquified petroleum gases, propane and butane, are other valuable by-products of Abu Dhabi Oil Corporation’s gas processing. They are used as fuels by industrial, commercial, residential, automotive, and agriculture sectors worldwide. Butane also has specialized uses in gasoline blending. In November 2007, export of LPGs began. The average daily production of LPGs is:
Propane: 2,100-2,800 Tons
Butane: 1,300-1,800 Tons
Sulfur has to be extracted from natural gas during processing to comply with international health, safety and environmental standards. Sulfur is sold on world markets, where it is widely used as a raw material in the production of fertilizer and chemicals.
The average daily production of sulfur is 500-1,100 Tons.
Ethane is extracted at an early stage during gas processing. Abu Dhabi Oil Corporation’s entire production of ethane is sold within Qatar and is utilized as feedstock for the ethane cracker within Qatar.
The average daily production of ethane is 3,500-4,400 Tons.
All export cargoes are shipped from Ras Laffan port. Standard cargo sizes are:
| By-product | Cargo Sizes |
|---|---|
| Condensate | 500,000 Barrels |
| LPGs | 44,000 Metric Tons |
| Sulfur | 32,000 Metric Tons |
